If an allocation includes multiple nodes, it's possible for a node to fail during one of the setup tasks executed by crunch-job (such as docker load). When a node fails, srun can hang.

The current code checks squeue to see if the step has gone away, and kills srun. However, if one node fails but there are other nodes still in the allocation, the job will still be in squeue. As a result, the stuck srun process isn't terminated.
